SPECIFICATION forming part of Letters Patent No. 317,596, dated May 12,1885.

Application filed December 1, 1884. (No model.)

T at whom it may concern:

Be it known that we, BENJAMIN D. TRAITEL and HENRY RUYTER, citizens of the United States, residing at New York, in the county of New York and State of New York, have in vented certain new and useful Improvements in Finger-Rings and other Articles of Jewelry, of which the following is a description.

Our invention relates to that kind of finger- Ic rings and other articles of jewelry in which are employed detachable initial letters, monograms, and other ornaments that are mounted or arranged on stones, enamel, or other grounds.

Previous to our invention it has been customary to secure in a removable manner initial letters upon the stones or other grounds of finger-rings by soldering the ends of two pins at opposite points of the letter, passing said pins through holes in the stone, and in the box or bearing therefor until the letter shall have come to a seat on the upper surface of the stone, and then securing the same in position by the use of two nuts screwed onto the 2 5 lower threaded ends of the projecting pins.

To this construction of finger-ring there are several material objections, principal among which are the following:

First. Considerable skill is required to solder 0 the pins to the letters in the exact localities in which they must always be secured in order that they may be passed centrally through the holes in the stones, and in the bearings or stone-supports, and receive at their lower threaded ends the screw-threaded nuts which have to be countersunk and fit neatly and entirely the holes drilled in the metallic stone support or box. As will be readily understood, any failure of the pins to pass other- 0 wise than axially through the holes in the stone and the box would not only prevent the proper counter-sinking of the nuts, but would besides render very liable the breaking off of the pins at the soldered joints during the 5 screwing on and attempted proper countersinking of the nuts.

Second. In the use of linger-rings constructed as above described thereis great liability of the letters being knocked from the pins by coming in forcible contact with hard surfaces, and also of being torn therefrom by catching into the clothing or other extraneous objects and breaking the union of solder between the letters and the pins.

Our invention has for its aim the production of a finger-ring or other article of j ewelry 0f the type referred to which shall wholly overcome the objections urged against the previous construction, and which shall be less costly ofmanufacture and more perfect in operation.

To these ends and objects our invention may be said to consist,particularly, in the combination, with the perforated stone or other ornamental ground and its support or box, of screws and initial letters or other ornaments provided with threaded holes to receive the said screws, all as will be hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a top view of a finger-ring embodying our invention. Fig. 2is a vertical longitudinal section taken at the line w w of Fig. 1. Fig. 3 is a vertical cross-section taken at the line y y of Fig. 1. Fig. 4 is a detail view of the initial letter and attaching-screws separated.

In the several views the same letters of reference designate the same parts.

'-A is the shank or band of the ring. B is the box or bearing. 0 is the stone,set within 8 said box, and E the initial letter, mounted or arranged on the upper surface of the stone.

As will be seen, vertical holes or openings or a are made through the box B in a direction lengthwise of the latter and about centrally 8 widthwise, and still smaller holes or perforations 0 c are formed in the stone 0, coincident with those in the box B.

Through the initial letter E are drilled two small perforations, b b, one at each extremio ty, lengthwise of the letter, and so as to register or come in line with the holes in the stone and in the box when the letter shall have been placed on the surface of the stone for securement in position. The holes or per- 5 forations in the initial letter E are screwthreaded and receive the threaded ends of the shanks of the screws 0 e,which, as will be seen, pass from the under side of the setting up through the holes a a in the box and holes 0 a mo in the stone. As neither the holes in the box nor those in the stone are threaded, it is only necessary for the shanks of the screws to be threaded for a distance from their points about equal to the length of the threaded holes in the initial letter. The larger'sized holes a a, made in the box,are for the purpose of admitting the seating of the heads of the screws, which must be countersunk below or flush with theunder surface of the box, so as not to injure the finger of the wearer of the ring.

In preference to forming the screw-heads with the usual slots across their entire faces, we form them about as shownthat is, with oppositely-disposed notches or cut-outs in the peripheries -of. the headsand use to turn them a tool formed with projecting points adapted to engage the notches. This construction is preferable, because the screw-heads, usually made of gold and necessarily thin, would not be quite as suitable for the purpose if made with the ordinary slot or nick across their faces.

In the manufacture of these rings we make the length of the screw from its point to the outer face of the head (or from extremity to extremity) exactly equal in length to the distance from the top surface of the letter at the locality of the threaded hole to the under side or surface of the box, so that when the parts shall have all been assembled together to make up a marketable ring the points of the screws will exactly fill the hole in the letter and come perfectly level with the upper surface thereof; and so that the outer surfaces of the heads of the screws will come substantially flush with the lower side of the box; and in practice we engrave the points of the screws, so as to in a great measure conceal their existence.

Interiorly of the box are secured two small rings, 2' i, the holes or openings through which are less in diameter than and are arranged in line with those in the box, and provide circular ledges or stops for the heads of the screws to abut against and limit their move ments.

Having described the construction of a ring embodying our invention, we will now describe the operation of putting the parts of the setting together. The box B having been drilled with the holes a a, and the stops it secured to the box interiorly, as shown and described, the stone 0, perforated at cc,is fitted within the box, and the letter E,with threaded holes I) b, is laid on top of the stone, and the series of holes in the box, stops, stone, and letter all made to register The screws 6 e are then passed through the holes in the box, the stops, and the stone, until they reach the under side of the letter, when they are screwed into the threaded holes thereof in the manner shown. Should it be desired at any time to substitute for the initial letter on the ring some other letter or ornament, (which is supposed, of course, to be threaded in the manner shown and described, and at the same 10- calities,) the screws are simply removed, the letter taken off, and the desired other letter or ornament put on in its place, and the screws reinserted.

It will be seen by our invention that we have provided a simple, cheap, and effectual means by which initial letters or other ornaments may be detachably secured to the settings of finger-rings, and one that is free from the objections incident to the constructions which existed prior to our invention.

XVe do not wish our invention to be considered as limited to any particular form or construction of box or bearing for the stone, nor to any particular form or shape of stone, nor to its use solely in connection with fingerriugs, as it will be readily understood that our invention is equally applicable to sleeve-but tons and other articles of jewelry.

Having now so fully explained our invention that those skilled in the art to which it appertains can readily understand and practice the same, what we claim as new, and desire to secure by Letters Patent, is

1. In a finger-ring or other article of jewelry, the combinatiou,with. the perforated box or bearing and perforated stone or ground, of a removable letter or other ornament pro vided with threaded holes and screws engaging therewith, substantially in the manner and for the purpose set forth.

2. In a finger-ring or other article of jew elry, the combinatiou,with the perforated box and perforated stone or ground, of the initial letter or other ornament provided with threaded holes, screws engaging therewith, and stops to limit the movement of the screws, substantially as and for the purpose set forth.

In testimony whereof we have hereunto set our hands this 24th day of November, 1884..
